His throw beat the Welsh Athletics' A standard of 60m for Glasgow 2014 and put him top of the British and European rankings in 2013 and sixth in the world. Morse is expected to compete at the Welsh Athletics International at the Cardiff International Sports Stadium on 31 July.

Morse later apologised for his remarks and tweeted: "It was very stupid and immature on my part... being an Olympian means a lot to me and I should know a lot better than to make accusations and stupid remarks about a fellow athlete. So once again sorry."

Cardiff-born Morse has moved back to Wales after being based in Sweden before London 2012 and has set his sights on fulfilling his potential in his chosen field event.

"I have decided to base myself in Cardiff again and it has gone well so far," said Morse.

"I have the European Team Championships, the Anniversary Games at the Olympic stadium and I want to make up for my disappointment there last year, and then it's Commonwealth Games in Glasgow and the European championships next year."
